Description
CATO manufactures 7-hydroxy-3,4-dihydrobenzo[b]thiepin-5(2H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
7-hydroxy-3,4-dihydrobenzo[b]thiepin-5(2H)-one (CAS 2226905-49-1), molecular formula C10H10O2S and molecular weight 194.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 7-hydroxy-3,4-dihydrobenzo[b]thiepin-5(2H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
